Nice!

Roman, I've checked out these changes, and there appears to be conflicting calculations between align_mag and align_mag_yaw.

• Align_mag or orientate preset is obviously based on the hardware designers component mounting of the magnetometer chip, and referenced by the arrow on the device. This setting should only be adjusted to suit the hardware specifications.
• While align_mag_yaw is a software setting used to adjust the mounting position of the device in the craft. Which uses the compass arrow as a reference marker for this purpose.

The problem I've observed when the flight controller board has a different Yaw mounting position. And the Yaw slider is moved to set the compass arrows direction according to its mounting orientation in the craft. Is the orientation preset become shaded and requires it to be changed to line up with align_mag_yaw. With it also locking up the Configurator.
This makes no sense, because the orientation preset should not be changed from the manufactures specification. But if it isn't changed the Gyro and Mag will clash.
And once orientation preset is changed to suit the tools requirements, it becomes a mess when trying to workout the actual align_mag position based on the arrow and magnetometer hardware..

I hope now everything works correctly:
